NOTE: The Cayman GT4 Race Headers do not include catalytic converters, and are recommended for track/off-road use only. In most vehicles, removing the catalytic converters may trigger a Check Engine Light. HOWEVER, in over 200 miles of testing, our development vehicle did NOT trigger a CEL with these Race Headers installed.
INSTALLATION NOTE: To ensure proper header seal, after initial heat cycle, tighten all exhaust bolts to the OEM torque specs.
